As the delivery continues, owing at nd With a c pl av n a Stufling box to the'difierent amounts of exposedarea atop- 11 for the reception of packing 12. which is composite sidesof the piston, the piston will be i 50 pressed by the jam nut 13.Extending longi forced downwardly from the position shown in tudinallyof the container or cylinder 9 and pro- Fig. 2 to the bottom of thecylinder or conjecting inwardly thereof and extendingthrough tainer,thus displacing or transferring the -mathe cap 10 is a tube 14 whichembraces andis .terial in the cylinder or.container to the opthreaded atits outer end onto the tube 15. posite side of .the piston anddepositing about The tube 14 is reduced in outside diameter as thepiston in/the cylinder orcontainer 9 a predetermined amount of material.In this operation, it is of course assumed that the valve 32 is closed.When it is desired to deliver the contents of the cylinder or container9, which is of course a predetermined amount, the Valve 32 is opened andthe tubes 14 and 15 rotated until the openings 24 and 25 do notregister. In such an instance, delivery of material through the inletdelivery pipe will ;cause the piston to move. upwardly relativelyv totheicylinder or container 9, thus forcing the material infront of thepiston outwardly through the outlet delivery pipe 33 and filling thecontainer or cylin v der behind the piston. The groove 20' is formed sothat in the reverse operation, when the 'move-' ment is initiallystarted, a passage -for theyes-t cape of the material fromthetube 15into the container or cylinder 9 will be provided. After the delivery ofthe predetermined amount, .upon 7 a closing of the valve 32, and thefurther delivcry of material through the pipe35, the reverse travellingof the piston will again be effected to again"load the cylinderforanother operation, asstated above. P '1 It is. believediobvious thatthe device may be used for direct lubrication or direct delivery fromthe-sourceof supply through thepipe35 and through the pipe 33- bymaintaining the valve 32 open while the openings24. and 25 are inregistration. 1

. Since the position of the piston relatively to the tubes 14 and 15 isfixed, it is evident that a mounting in which the cylinder is floatingor in which these tubes are floating is necessary 1 In the form shownin:Fig. 1, 'Ihave illustratedthe invention used with an .oil deliverypump 3'7 which is operated by-the crank 38.;to deliver oil from thecontainer 36. The delivery pipe '35 is connectedto the tube 15, inthe-manner indicated in Fig. 2, and the 'va1ve32" is used for thepurposes described relatively to the valve 32. A flexible outletdelivery; tube 39 correspondsto the. tube 33. 1:

In the modified form, I have shown a. form which in structuraldetail-differs somewhat from the structure shown in Fig. 2, but which inoperation is quite similar "and substantially the same. The tubes 14 and15- with the openings 24 and 25 formed therein may be said toconsti-:tute a valve arrangement and inthey modified form the valve arrangementdiffers in that it is of the needle type. a

' In the modified form; I; provide a metering or measuring container orcylinder9" .into which is projected slidably through the .cap 41-,- thetube 40,-which is connected to the inlet delivery pipe '35. Threadedinto the endof the pipe .40 beyond the openin'gs62 formedin thepipe40.15 a cup shapedfitting 42 which serves to eiiect a; clamping ofthewashers l81betweenthe .rigid discs or washers43 and 44. 1 A; circularflange 14 projects outwardly. from one face of the. disce i and acircular flange 42 projects outwardlyfrom one end of. the fitting 42; Apipe '45 is projected slidably through the cap 63,.and this pipe 45 isprovided with the reduced 'th'readedwportion 46 which threads into-.the

' fitting 42...- Projecting-from the reducedthreaded portion 46 is aneedle valve forming. portion 4'] having .a radial passage 49'providedtherein communicating with the axial passage 50in the reduced portion46,-which communicates .withthe passage or bore 51 in .the tube 45." Theneedle valve is tapered to serve as aclosure for the opening 48 which isformed centrally inthe cup shaped fitting 42. A valve 64 is mounted onthe outer end of the tube 45 to control communication of the tube 45with the outlet delivery pipe 33. Radial openings or passages 52communicate with the passage 51.

In operation, when the tube or pipe 45 is rotated to bring the needlevalve 47 into closing position relatively to the opening 48 and materialunder pressure is delivered to the pipe 35, this material will flowoutwardly through the opening 62 and fill the cylinder or container 9and force a movement of the piston relatively thereto until it arrivesat the upper end of the cylinder. This will, when the valve 64 is open,force outwardly through the delivery pipe 33 the material'which waswithin the cylinder 9" above the piston, thus effecting a delivery of apredetermined amount of material under presf-sure. To effect a movementof the piston to the other end of the cylinder and again load thecylinder foranother operation, it is but necessary to close the valve64, rotate the pipe 45 relatively to the fitting 42 until the needlevalve is "moved to open position, upon which the material deliveredthrough the pipe 35 will flow through theopening is; through thepassages wand 50 and outwardly'through the openings 52. On account ofthe larger exposed area .of the piston on one side than the other, thiswill cause the piston to move downwardly relatively to the cylinder 9"and thus move the parts to position for another operationinvolving thedelivery of a predetermined amountoimaterial through the outlet deliverypipe33. V It is obvious that the device may be used for direct deliveryfrom the pipe 35 to the pipe 33. by maintaining the needle valve in openposition while the valve 64 is open. Since the piston is fixedrelatively to'the pipes or tubes 40 and 45, it is obvious eitherthatthese pipes must'be of afioatingnature or that the cylinder or container9" is mounted in a floating condition.

By positioning a number of loose washersol' spacers 87 in the cylinderor container 9, or 9", the capacity of the cylinder maybe varieddepending upon the number of washersor spacers which are used. 7 1
